A recent study has revealed that flight attendants and pilots face a higher risk of radiation-related cancers compared to individuals working with radioactive materials. The study focused on cosmic radiation, which originates from space and poses a greater threat to individuals flying at high altitudes due to increased exposure.
Published in JAMA Internal Medicine, the study analyzed national data from over 12 million death certificates, examining cancer death rates associated with radiation exposure. Occupations such as flight attendants and pilots were found to have the highest percentage of deaths from radiation-related cancers among more than 500 occupations studied.
The study’s authors highlighted that flight crews’ excess risk of skin cancer is not solely attributed to sunny layovers but also to factors like cosmic ionizing radiation at cruising altitude and circadian rhythm disruption from night-shift work. Flight attendants were found to have approximately 50% higher odds of dying from radiation-related cancers compared to the general working population, while pilots had around 36% higher odds.
While the study acknowledges limitations such as the inability to quantify specific radiation exposure levels for each individual, it emphasizes the importance of recognizing and addressing the risks associated with radiation exposure in the aviation industry. The authors recommend increased awareness and monitoring of radiation exposure levels among flight crews, suggesting that regular skin examinations and mammograms may be necessary for individuals working in high-altitude settings.
The findings underscore the need for heightened vigilance among healthcare providers caring for pilots and flight attendants, with a focus on early detection and management of radiation-related cancers in these at-risk occupational groups.
